有機水產養殖之展望

有機水產養殖之展望:探討國際趨勢與國內未來發展
文 / 陳永松(國立宜蘭大學動物科技學系助理教授 / 有機產業發展中心)

國立宜蘭大學動物科技學系助理教授陳永松在魚推月刊295期以及296期上發表了一篇「有機水產養殖之展望:探討國際趨勢與國內未來發展」,提及有機水產魚類是未來漁業發展的重要趨勢。

AutoPot零排放水耕系統

AutoPot零排放潮汐水耕系統 植物自動潮汐水耕,屬於Aero-Hydro garden的一種,它由水盆,水箱和潮汐閥組成.它可以控制,它可控制潮汐二個水位.低於汐水位-自動供水;達到潮水位-自動停水,停水期間以水的蒸散作用讓植栽吸收,當水位下降到汐水位時(可能是幾天或幾小時,依不同植栽而定)
土壤本身永遠保持潮濕但不浸濕的狀況, 使耐旱,好濕植物都能正常吸氧,不會爛根.潮汐水耕對不同季節,不同作物,對同一作物不同的生長階段是不同的, 間歇澆水器會自動按植物實際需求完成潮汐期長短的轉換.這有別於一般自動澆水器的想法.真正做到按植物實際需求供水.工作其間不用電.適用於無土栽培溫室,陽台,屋頂花園.澆水不用人工管理.更重要的是水源零回收零排放

養耕共生和都會農場可以創造綠色就業嗎

養耕共生和都會農場可以創造綠色就業嗎?
By Charles Redell報導, 2011/9/16 In the wake of President Obama's jobs speech last week, the national conversation is intently focused on growing jobs -- and particularly green jobs -- in the weak economy.
在上週歐巴馬總統就職演說後,國家在疲弱的經濟中專心發展綠色就業機會。
This week, we saw a new twist on green jobs, and one that promises something of a Holy Grail of sustainability: Creating jobs to grow sustainable food products at an economically viable scale that will be consumed in the local foodshed. 本週我們看到了一個新的綠色就業的企機,並承諾永續發展的使命:創造綠色就業,從永續的糧食產品創造經濟規模增家本地食材的消費規模。 That's the pitch from the Recirculating Farms Coalition (RFC), which launched earlier this week. The group says the type of farms and farming it promotes can achieve those goals and more, including urban job creation. 這是農場聯盟(RFC)的一大突破,稍早本週該組織說,都會農場和都會農業,絕對可以實現創造城市 的就業機會。 The coalition is promoting sustainable, closed-loop farms that grow local, fresh food and, it says, create green jobs using clean, recycled water in place of so…

Taiwan Luminous Angelfish

Taiwan Genetic Engineering, Luminous Angelfish
台灣螢光魚 The most recently created fluorescent fish are angelfish - the biggest and brightest transgenic glowing fish in the world so far.
Taiwan's largest exporter of ornamental fish, the Jy Lin Company, says it has successfully inserted a fluorescent protein gene into the reproductive organs of the fish. It allows them to produce glowing offspring.
The company says its new breed of fish took more than three years and approximately 10 million Taiwan dollars to develop because the reproductive cycles of medium-sized fish are harder to control than their small-sized counterparts.
The angelfish are members of the biological family Cichlidae.

Cichlids make up the majority of fish seen in most aquariums.
"With the medium-sized cichlid fish, its biological cycle cannot be controlled by artificial lightings. Plus the low number of fertilized eggs makes the collection of fertilised eggs a challenge - it will take a very long time with the …
